The AVR series provides peak outputs to 200 Volts, with rise and fall times of 2 or 10 ns. Pulse widths as narrow as 10 ns and as wide as 5 us can be provided. For applications requiring narrow pulses or fast response times, the AVR-A-1-S2 family offers pulse widths of 10 to 200 ns, with a minimal 30 ns propagation delay (when externally triggered). The -C versions provide output pulse parameters similar to those of the -B models, but do not include the GPIB or RS- 232 interfaces (i.e. no computer control or LCD display). The output parameters are controlled by front-panel range switches and one-turn controls. All models require 100- 240V, 50-60 Hz AC power.
